To all may concern: Be it-known that I, DANIEL lM.' Lemans, l

Toledo, county of Lucas, State of Ohio, have invented certain new anduseful Improve- Spraying 1.5 1910, for spray ments in Spraying Devicesand Means for Controlling the Same,of which the following is aspecification.. 4

This invention relates to improvements in devices and means for controlling theisame. A It relates specifically to improvements in certaindetails in the structure appearing in my Patent No. 962,512, dated .lune28,

heads, andy inotheri par#- ticulars to imp oved means for vcontrollingspray heads aitomatically, intermittently and from a dist nt point.

The objects are, First, to provide an im- 20. proved controlhng meansfor" such spray heads, preferabl consisting of Huid pressure devices. .vecond, to provide an improved means for intermittently controlling suchspray heads. Third, to provide iin-- proved means for automaticallycontrolling such heads' whereby, when they are released, they willreadily openy for ushing .pur poses. Fourth, to provide` improved4 meansfor simultaneously controlling a number of' heads froml one place,whereby vthey will be' evenly andaeiiectively controlled andalsoflushed. Fifth, to` provide improved means for controlling the heads atintervals wheref by the flushing can bel vtimed eiectively.

Further objects, and objcts relating to structural details, `wil1definitely 'appear from the-detailed description tolfollow- I accomplishthe objects ofV my. invention 'by the devices and means described in thefollowing specification. The invention is clearly defined and point-v edout in the claims@ A structure embodying the features "of my invention.is clearly illustratedv in the accompanying drawing, forming a part ofthis specification, in which.: Fi ure 1 is a detail plan'view of myimprovide :apparatus inposition in its preferred form, portions of thecontrolling pipes-and supply pipes being broken siway.y

Fig. 5 is a .plan view' of thestructure appearing in F1g. 4. Fig.v 6 is. a detail view of anothermodification in which the control is by motor cylinder with connections.Fig. 7 is a detailsectional view of a controller consisting of adiaphragm ino-tor and connection.

Fig..` 8 v is a' detail view oi the valve construction as it iscontrolled bv these modied devices. The preferred construction is by asappears ln the drawing, all of thesectional views `vare taken looking inthe direction of the little arrows at the ends 'of the section lines,vand similar characters of reference refer to sirlni-v lar partsthroughout the several views.

Considering the numbered parte of. the drawing, vthe main pipe l isprovided at intervals with'spray heads. These are secured thereto by aflange 2 having a screwthreaded nipple which receives'the body or shell3 of the spray head. Aspider extends across this shell, and to it issecured a central column 51 on which reciprocates the valve di'skl. Thisvalve disk is formed onv its contacting side with a -parabolicallycurved surface, as described in my patent -above referred to. The valve4 is connected to the piston et. -Thisvalve disk and piston 4l`reciprocate on the column 5. The piston .4 in'.the cylinder 6 isprovided with a suitable jpacking, preferably consisting of a washer as4". Air is delivered under pres'- sure and under control through thepipe or tube 7, which is secured on to the nipple 8,- ,fthe passage 9 tothe cylinder being through the end of the column 5 and'then laterallylto the outer end of the cylinder. The pipes for the entire series ofvalves are connected toa common source o supply 4Q in?l directly throughpipes -10 and 10, whereby thesame can-.be controlled and thus -securethe iushing of all'the valves in successivel of an-air brake, all -ofthe spray heads on that connection will be opened by the pressure of thewater against the Valve disk, and,

' when'the pressure is turned on it will be circular reservoir 40.

vArranged about the reservoir 40 are a series p connection 47 to anelectric motor 48.

of three-Way cocks 42, which are controlled by a gear 43. This gear 43is actuated by a worm 44, Which Worm is in turn actuated by a worm gear45, which is driven by a Worm 46, which worm is driven by suitablerlelelt e group of three-wav cocks 42 (four in this instance), aregeared so as to open and close successively at regular intervals. One ofmy devices giving especially good satisfaction, 1s y timed to open eachof fourthree-'way cocks once in four minutes. Of course, when thethree-Way cock in any particular group is openedto the air, the fluidpressure is at once relieved in said three way cock and in theconnections thereto and the group of Spray heads connected therewith,and the piston 4 is pushed into the cylinder 6, of each of the sprayheads of that group by the action of 'the water against the .valve 4,which at once flushes the valve and frees it entirely from all sediment.As soon as the three-way cock is opened to the fluid supply again,thevalve is pushed to position by the fluid pressure anda thin sheet ofwater is delivered transversely to the head in a manner especiallyeffective for cleansing air that is passing through an air purifier orwasher. In some instances, the fluid pressure will be supplied by an aircompressor.

In Fig. 4, the connection to the valves is as shown in my .Patent No.962,512, but it is controlled by an electromagnet 23, the core 22 ofwhich. is connected by a suitable link 21 to the rod 12 which connectsto the actuating lever 11 of one of these valves, such as I'illustr'atein my patent referred to. A pair of connected parallel rock shafts 20',13 are provided, having parallel arms 19 and 14 connected by a rod 15disposedthrough guide bracket 18. A spring 16 on said rod acts againstthe collar 17 and abuts trolled by'a time switch 24 which controls thecircult 25-26.` In Fig. 6 is illustrated a structure whereln thecylinder motor'is connected by an arm- 30 to one of the bell cranks19,-20 and actuates the same in that Way. The motor cyll inder 27 isprovided with a piston 28, which is connected by a piston rod 29 andlink 31 to an arm 30, which actuates the bell crank 19- 20, asindicated.

phragm, in place of a piston, is made use of, the same consisting of ashell 32 with a dia- --phragm 33 therein contained, which diaphragm 1sclamped within the shell by the ring'34 which bears the spider 35through` which the pitman or iston rod connections 36 connect by a link3 toan arm 38 for ac tuating the bell cranks 19-20 in the same way' inwhich it is actuated by the solenoid appearingrin Fig. 4. The detailsofthe parts only are shown and the full connections omitted.

It will, of course, be understood that fluid.`

pressure is to be supplied to the motor cyl` inder 27 of Fig. 6 or thepneumatic motor of Fig. 7 from some suitable source of fluid pressuresuch as is shown in Fig. 1. Preferably this is arranged for automaticcontrol at predetermined intervals and in groups. However the sprayheads may also be controlled automatically so that all of the sprayheads vare flushed at once at predetermined intervals rather than ingroups. It may also be arranged so that they control of the spray-headsis not automatic, that is, it does not occur at predetermined intervalsbut they may be controlled by the turning of a cock at some distantpoint, all of the spray heads being controlled from a central point.

.- In Fig. 7, a pneumatic motor with a da?,

direct acting motors referred to,v appear in Fig.. 8,v in which an arml1 islpivoted to actuate the valve which is on the pillar-5';

and onthe pillar 5 corresponding to the.

pillar 5 of the preferred construction, is provided a flange 5", whichis acted upon by a coiled spring 5', all as clearly appears in Fig. 8,and alsol as appears from the structure of my patent above referred to.
